New Build Help #146

Closed c73martin closed 2 years ago

c73martin commented 2 years ago

I recently tried to get a op25 running on pi 3b+, I am going to paste a copy of Stder file, but I seem to be way off Freq from Radio Reference control channels. I attempted to use GQRX and locate the highest peaked channel in the vicinity and was able to get a lock and list of voice channels but no audio and see the system does lose control channel due to a time out. Any help would be greatly appreciated. I also am unable to get any audio but assume that is due to poor setup.

By default op25 assumes a cqpsk compliant modulation since this is the most commonly seen variant in use. Some stand-alone (non-simulcast) P25 FDMA (phase 1only) systems have c4fm modulation that doesn't play well with the default demodulator and under these circumstances you might try using "-D fsk4" on your rx.py command line.
